Re: [stunnel-users] stunnel through elb.. need packets sent semi-frequently
Hi I'm not sure this will work, but have you checked the option TIMEOUTidle = <num_seconds> ? Sounds to me like the setting you might be looking for ----------------- Leandro Avila ----- Original Message ----- From:Matt Wise <mwise@netflix.com> To:"stunnel-users@stunnel.org" <stunnel-users@stunnel.org> Cc: Sent:Thursday, April 7, 2011 6:04 PM Subject:Re: [stunnel-users] stunnel through elb.. need packets sent semi-frequently I'm using stunnel to pass some data through an Amazon ELB. Unfortunately, there are times when the session times out due to packets not passing for 60 seconds (an amazon ELB timeout). I'm wondering whether theres some way I can configure stunnel itself to pass some whitespaces or something back and forth every few seconds to make sure the session stays open and live? (and yes, I'm posing the same question to the app developer who's ap we're passing through.. but I'm looking at both avenues.. ) _______________________________________________ stunnel-users mailing list stunnel-users@stunnel.org http://stunnel.mirt.net/mailman/listinfo/stunnel-users

As far as I understood, TIMEOUTidle is the opposite of the feature Matt is looking for: After TIMEOUTidle expires without any traffic, stunnel closes the connection in order to clean up stale connections. However, Matt seems to be looking for a feature to produce dummy traffic for long-running and idle connections.

Correct! I need dummy traffic that Amazon sees as real traffic... white spaces, or something. Maybe even a config that lets me send those '—MARK—' messages across the wire, but without writing them to any of the actual log files would be simple enough? —Matt On Apr 8, 2011, at 2:58 AM, Ludolf Holzheid wrote:
